Workflow

4 Steps to Launch a WhatsApp Campaign

1. Import & Segment

Upload your opted-in customer lists and divide them by tags, tags history, or geographic location.

2. Draft Templates

Write message templates with dynamic placeholders and buttons, submitting them to Meta for instant approval.

3. Schedule & Test

Perform an A/B test on a small test group first, then schedule the winning message variation.

4. Analyze Performance

Monitor delivery metrics, button clicks, and conversation read rates from your central dashboard.

FAQs

Campaigns — Frequently Asked Questions

What types of campaigns can I run on WhatsApp?

You can run promotional campaigns (product launches, seasonal sales, event invitations), re-engagement campaigns (abandoned cart reminders, win-back offers), informational campaigns (product updates, feature announcements), and loyalty campaigns (rewards programs, VIP offers). All require opted-in contacts and pre-approved templates.

How does A/B testing work?

Create two or more template variations and split your audience. StartMessaging sends each variation to a test segment first, measures performance (delivery rate, open rate, click rate), then automatically sends the winning template to the remaining audience. You can test different copy, images, buttons, and CTAs.
